2 Claims. 1

This invention relates to new and usefullimprovements in al door hinge.

More specifically, the invention proposes a construction of a closurecharacterized by a frame, a door in the frame and hidden hinges connectning-the door to the frame.

Still further the invention proposes a closure as aforesaid, in whicheach of the hidden hinges includes a bearing retainer in the frame, acylindrical sleeve in the retainer, and ball bearings between the sleeveand retainer.

Still another object of the invention is to provide a closure, asaforesaid, in which the hidden hinges permit the door to be removed fromthe frame at will, without the use of special tools andY withoutremoving any part of the hidden hinges from the door or frame.

Another object of this invention is to provide a hidden hinge, asaforesaid, having as a feature thereoLan adjustable door stop.

For further comprehension of the invention,

and` of the objects and advantages thereof, reference will be had to thefollowing description and accompanying drawings, and totheappendedclaims in which the various novel features of the invention are moreparticularly. set forth.

In the accompanying drawings forming a rna-l terial part of thisdisclosure:

Fig. 1 is a fragmentary foreshortened vertical sectional View of aclosure embodying the present invention, parts being shown in full.

Fig. 2 is a view similar to Fig. 1 oi` a closure constructed inaccordance with amodification of this invention.

Fig. 3 is a view similar to Fig. l showing a top hidden hingeconstructed in accordance with a modification of this invention, havingas a feature thereof, an adjustable door stop.

Fig. 4 is a plan view of the structure of Fig. 3.

The closure shown in Fig. 1, includes a frame I0, a door II, a tophidden hinge I2 and abottom hidden hinge I3.

Hinge I2 includes a bearing retainer I4 which is sunk into the frame Iabove one corner portion of door I'I. Retainer Ill has a cylindricalbase, two spaced horizontal raceways I5- in the wall of the bore, and anannular shoulder I6 extending inwardly from the bottom edge of the bore.A cylindrical sleeve Il, having an axial bore throughout its length, isdisposed in retainer I4, and is supported on top of shoulder I6. Ballbearings I8 are disposedin raceways I5 between sleeve I 1 and retainerI4. Thus sleeve Il is free to rotate in retainer I4 and is preventedfrom.

dropping out of the retainer by shoulder I6. The

2 inside diameter of the bore of sleeve Il is similar to the insidediameter of the bore of shoulder I6.

A casing I9 is sunk into door il' in line with the retainer I4. It hasan axial bore 2G open at its outer end at the top of the door II andclosed at its inner end by a horizontal wall 2I. Opposed elongated slots22 are formed in the side wall of the casing.

A coil spring 23 is disposed in bore 2li, seating on wall 2I, and a pin24 is also disposed in bore 2i) on top of spring 23. Pin 24 hastrunnions 25 which extend into slots 22. When the trunnions are at thetop of the slots as shown in Fig. 1,

the spring 23 will be under some compressiony thereby holding the pin 24in its full upward position. The trunnions may be formed by a pin forcedthrough a hole in the pin 24. The pin 24 and casing I9 will beassociated before the casing I9 is sunk into door II. A row of recesses26 are formed in the pin 24 at right angles to the trunnions 2.5 and inthe portion of the pin adaptedlto extend above the casing I9.

These recesses may be formed by drilling into the pin 24. They are foremployment in removing the door from the frame. This may be accomplishedby swinging the door at right angles to its position shown in Fig. 1,inserting a pointed tool such as an awl between the top of the door andthe adjacent part of the frame and into a recess 26, moving the pin 2lidownward until another awl can be inserted into another recess and so onuntil the pin Z4 is entirely out of sleeve Il and retainer I4. The topof the door may then be pulled out of the frame and the door lifted, aswillV presently appear, to disconnect the bottom hinge and therebycompletely remove the-door from the frame.

The bottom hinge I3 includes a bearing retainer 2l having a verticalcylindrical bore 28 open at its top and closed at its bottom by a wall29. Two horizontal spaced raceways 30 are formedv in the cylindricalwall of the bore.

A thrust bearing 3l is disposed in the bottom of the bore 28. A hollowcylindrical sleeve 32 having an axial bore open at its top end andclosedA at the bottom by a wall 33 is disposed in the bearing retainer2l with its wall 33 seating on top of the thrust bearing 3|. Ball bearings 34 are disposed in raceways 3) between sleeve 32 and retainer 2i.If desired a retainer identical to retainer I4 may be used, thrustbearing 3| being supported by shoulder Iii. Further, a sleeve identicalwith sleeve I'I may be used,

the bottom edge of sleeve I1 seating on the thrust bearing.

A casing 35 is sunk in the bottom of door Il. It has a cylindrical bore36 open adjacent the bottom f the door I I and closed at its other endby a wall 31. A pin 38 removably connects casing 35 with retainer 21. Ithas a cylindrical portion 39 disposed in bore 36 with its top end inengagement with wall 31, a reduced portion 49 is disposed in the sleeve32 and a shoulder 4I' between portions 39 and 40 in engagement with thetop edge of sleeve 32.

It is contemplated that there will be enough lateral play between theparts of the hinge I3 to permit the top of the door to be moved out ofthe frame. The door may then be simply lifted so that casing 35 comesaway from pin 38, pin 38 staying with retainer 21. If desired, means maybe provided (not shown) so that pin 38 will stay with casing 35 andleave retainer 21 when the door is lifted. For instance a casingidentical to casing I 9 may be employed and the pin 38 may be providedwith trunnions for sliding movement in the slots of the casing.

From the above description it will be apparent that the hidden hinges I2and I3 provide a simple means for hinging a door to its frame in such amanner that the door may readily be taken out of its frame without theremoval from the door and frame of any parts of the hinge.

In the modication of the invention shown in Fig. 2, the construction ofthe top hinge 42 is similar to the hinge l2 except for the portion ofthe top hinge sunk in the frame. Parts of hinge 42 similar tocorresponding parts of hinge I2 will be indicated by like referencenumerals with a prime mark or an accent added, and as to like parts nofurther description thereof is deemed necessary.

The retainer 43 of hinge 42 is sunk in frame I 0 and has a cylindricalbore 44 and an annular shoulder 45 extending inwardly from the bottom ofthe bore 44. A raceway 46 is formed in the shoulder 45 and ball bearings41 are disposed therein forming an end thrust or support bearing. Asleeve 48 having an axial bore 48 and a horizontal raceway 59 in itsouter face is disposed in bore 44 with its bottom edge supported on theball bearings 41. Ball bearings I are disposed in raceway 50 betweensleeve 48 and retainer 43. The bottom hinge for the door II' isidentical with the hinge I 3,

The operation of this form of device is similar to the closure shown inFig. 1. While the retainers have been shown disposed in the frame, thehinges may be reversed if desired and the retainers disposed in thedoor.

In the modification of the invention shown in Figs. 3-4, theconstruction of the hinge is similar to the hinge shown in Fig. 1 butdistinguishes therefrom as follows:

A pin 52 having serrations 53 in its upper end is provided, theserrations mating with serrations 54 formed in the bore of a sleeve 55disposed in a bearing retainer 56. The top edge of the retainer 56 is'provided with shoulders 51 and 58 and sleeve 55 has a linger 59overriding the lowermost portion of the top edge of retainer 56 andadapted to abut shoulders 51 and 58 respectively depending upon thedirection in which the door is opened. Other parts of the closure ofFigs. 3 and 4 similar to corresponding parts of the closure of Fig. 1are indicated by like reference numerals with two accents added.

Finger 59 is shown in the drawing disposed midway between shoulders 51and 58, thus allowing the door to swing an equal amount in eitherdirection. Shoulders 51 and 58 limit the swing of the door and will stopit in a predetermined position This is desirable in doors having hiddenhinges because the door is disposed midway in the frame and if it isswung too far in either direction it will hit the frame and will tend torip the hinges out of the door.

The position of finger 59 may be adjusted, if desired, to change theamount that the door may be swung. This is of value, for instance, whereit is contemplated that the door will only be swung in one direction,from its position in the frame. To make this adjustment, the pin 52 canbe assembled with the sleeve 55 with the linger 59 disposed at anydesired angle relative to the trunnions 25" of the pin. The serrations53 and 54 provide a simple means of accomplishing this adjustment.

The maximum'angle that the door may swing through will normally be lessthan degrees due to the fact that the door is disposed in the frame. Asthe angle between the shoulders 51 and 58 is greater than 180 degrees,it is therefore possible to obtain a maximum swing in either direction.

While I have illustrated and described the preferred embodiments of myinvention, it is to be understood that I do not limit myself to theprecise constructions herein disclosed and the right is reserved to allchanges and modifications coming within the scope of the invention asdened in the appended claims.

Having thus described my invention, what I claim as new, and desire tosecure by United States Letters Patent is:

1. A hinge mounting for supporting a door in a frame comprising a hiddenhinge at the top of said door pivotally connecting said door to saidframe, said hinge including a sleeve retainer in said frame, a sleeve insaid retainer adapted to rotate therein, said sleeve and retainer havingcoacting parts limiting the extent of rotation, and a pin having aportion keyed in said door and another portion keyed in said sleeve forrotation therewith, whereby said sleeve limits the angle of swing ofsaid door.
